With the deadline for underclassmen to declare for the 2019 NFL draft come and gone, we have a clearer picture of which prospects could find themselves selected in Round 1 on April 25.

Most prospects in this year's class had already made their intentions to take their talents to the NFL known, but there was some last-minute activity near the deadline.

Alabama safety Deionte Thompson didn't declare for the draft with his teammates at the Alabama press conference held on Jan. 11 but announced via Twitter the following Sunday that he wouldn't be returning to the Crimson Tide. His teammate, Mack Wilson, also projected to be a first-round pick in April, did the same via his Twitter account.

Thompson and Wilson are two of the many first-round defensive prospects teams will be eyeing with their selections in 2019. The first-round talent also includes a handful of intriguing quarterbacks, skill position prospects and offensive linemen.

With the draft order even further settled following divisional-round weekend, let's take a look at how teams might look to select in the first round this spring.

There's no such thing as a sure thing when it comes to the NFL draft, but Ohio State's Nick Bosa sure is close.

Some draft analysts suspect the Arizona Cardinals may try to trade out of the No. 1 spot to amass more draft capital, but the vast majority see them being unable to pass up this premier pass-rusher, especially with the changes on deck for their defense.

"Bosa is going to be tough to pass up, as he is an elite pass-rusher," Kiper wrote. "New defensive coordinator Vance Joseph is expected to switch this defense back to a 3-4, and Bosa has the versatility to play multiple spots."

After suffering a core injury last season, Bosa was limited to just three games. The year before, he had 34 tackles (16 for loss), 8.5 sacks, two passes defensed and a forced fumble.

Pass-rushers are becoming perhaps the most valuable players in the NFL draft; an exceptional one can change the face of a defense. So it's no surprise that the San Francisco 49ers would look to land Josh Allen in this scenario after Bosa comes off the board at No. 1 overall.

There's no question that San Francisco needs to surround quarterback Jimmy Garoppolo with some offensive playmakers in order to help him succeed, but no players fit that bill at No. 2 overall.

The 49ers could move down and amass more draft capital in the process, but passing up a player with Allen's talent would be a hard pill to swallow.

Allen's college success was recognized by accolades including being named a consensus All-America selection, the SEC's Defensive Player of the Year, the Chuck Bednarik Award winner and the Bronko Nagurski Award winner as the best defensive player in college football.

His eye-popping 2018 season at Kentucky saw him amass 88 tackles, 17 sacks, five forced fumbles and four pass deflections.

Allen would also give the 49ers much-needed versatility in the front seven, offering the ability to line up as their strong outside linebacker in base defense, as well as at defensive end.

Speaking of targeting offensive talent early in the draft, this is a bold projection for the New York Jets and one that many won't agree with. That's OK.

The Jets are desperate for weapons for young quarterback Sam Darnold. If they want to target a wideout at No. 3 overall, there's a dizzying array of options from which to chooose: Ole Miss' D.K. Metcalf or A.J. Brown, Harry, Oklahoma's Marquise Brown.

However, what New York needs is a bona fide No. 1 outside threat, which makes the Jets more likely to home in on 6'4" Metcalf or Harry.

In this scenario, it's impossible to say anything definitively about the wideouts available until we see how they perform at the NFL scouting combine.

Harry impressed with 73 receptions for 1,088 yards and nine touchdowns with the Sun Devils last season, but the main thing he needs to demonstrate at the combine is speed.

If Harry runs an impressive 40-yard dash time, he could find himself as the first receiver taken off the board in April.
